Field Descriptions
Region This is a preconfigured field that you cannot change.
Country Specify a country by making a selection from the drop-down list.
Operating Frequency This is a nonconfigurable field. The ra
dio’s operating frequency is fixed at
2.4 GHz.
Mode Specify the wireless mode in the 2.4-GHz band by making a selection from the
drop-down list:
• g an
d b. In addition to 802.11b- and 802.11g-compliant devices,
802.11n-compliant devices can connect to the wireless access point because
they are backward compatible.
• g o
nly. 802.11g- and 802.11n-compliant devices can connect to the wireless
access point, but 802.11n-compliant devices function below their capacity in
802.11g mode. 802.11b-compliant devices cannot connect.
• ng.
This is the default setting. 802.11g- and 802.11n-compliant devices can
connect to the wireless access point. 802.11b-compliant devices cannot
connect.
• n o
nly. Only 802.11n-compliant devices can connect to the wireless access
point.
Channel Spacing For the ng and n only modes, specify the channel spacing by making a selection
from the drop-down list:
• 20/40
MHz. Select this option to improve the performance. Some legacy
devices (that is, devices that function only in b or g mode) can operate only in
20 MHz.
• 20MHz. Se
lect this option if your network includes legacy devices. This is the
default setting.
Note: The channel spacing is fixed at 20 MHz for the g and b and g only modes.
Control Side Band
Note: ng and n only
mo
des only
For the ng and n only modes, when you have selected a channel spacing of
20/40
MHz, you also need to select the control side band from the drop-down list.
The extension channel that is specified by the control side band is four channels
above or below the main channel.
• Lo
wer. The radio can use a lower channel (in the 1–9 range) as its extension
channel. Use this setting when your main channel is in the 5–11 range. Lower
is the default setting.
• Upper. T
he radio can use a higher channel (in the 5–13 range) as its
extension channel. Use this setting when your main channel is in the
1–7 range.
Note: This field is not applicable when the channel spacing is set to 20 MHz.
Current Channel This is a nonconfigurable field that sh
ows the current channel if you have
selected Auto from the Channel drop-down list.
